A thermocouple is a temperature sensor made from two different metal wires joined at one end. When this junction is exposed to heat, it generates a small voltage that correlates with temperature. Used across industries from aerospace to manufacturing, thermocouples are valued for their simplicity, [...]

A thermocouple functions by leveraging the Seebeck effect, where two different metals joined together to create a voltage when subjected to varying temperatures. This generated voltage directly corresponds to the temperature difference between the heated (measuring) junction and the cooler (reference) end, allowing thermocouples [...]

A thermocouple is a temperature-sensing device that operates on the principle of converting temperature differences into electrical voltage. This simple yet powerful tool consists of two wires made from different metals, joined at one end to form a junction. When this junction experiences a [...]

Thermocouples generate voltage through the Seebeck effect, a principle where a temperature difference between two dissimilar metals produces an electromotive force (EMF). This voltage is proportional to the temperature gradient, making thermocouples reliable for industrial and scientific temperature measurements. A thermocouple consists of two [...]

William Nash and Eric Yeager – Cleveland Electric Labs; Twinsburg, Ohio As a designer and manufacturer of thermocouples, the most commonly asked question we receive is: How long should my thermocouple last? If you’ve ever wondered, “how long should thermocouples last?” you’re not alone. [...]

Thermocouples: Precision Temperature Sensors for Industrial Applications Thermocouples are vital instruments in industrial applications, providing precise temperature measurement through voltage potential. These sensors are made from two dissimilar metals, joined at electrical junctions. When exposed to varying temperatures, the junctions produce a voltage that [...]

Introduction to Platinum Thermocouples A platinum thermocouple is a high-precision temperature sensor engineered for applications that require accurate and stable measurement at extremely high temperatures. Made from premium thermocouple wire platinum and platinum-rhodium alloys, it delivers exceptional reliability and long-term stability, making it ideal [...]

Thermocouple History Thermocouples operate based on the Seebeck effect, a principle discovered by Thomas Johann Seebeck in 1821. This effect explains how an electromotive force (EMF) or voltage is generated when two dissimilar metals are joined at two junctions with a temperature difference between [...]

Thermocouples are essential for accurate temperature measurement in a wide range of industrial applications, but many users wonder, do thermocouples go bad? The answer is yes. Over time, factors like mechanical damage, excessive heat, and contamination can cause thermocouples to fail. Knowing why thermocouples [...]
